Aquaculture is one of
the fastest growing and promising sectors of food production all over the
world. In commercial aquaculture, it is very important to elevate disease
resistance, feed efficiency and growth performance of cultured aquatic species.
If these are realized, overall production costs would be remarkably reduced. Antibiotics
has been widely used in aquaculture to alleviate infectious diseases or to
promote growth performance. On the other hand, indiscriminate use of
antibiotics and some chemical drugs in aquaculture has led to potential
negative effects on the environment as well as human health. Therefore,
functional dietary supplements, such as prebiotics, probiotics and synbiotics
have been increasing importance as an environment friendly method to improve
the health of fish and crustaceans. In this review, the effects of prebiotics
are focused. Prebiotics are nondigestible feed ingredients that can positively
affect the animal organism by stimulating the activity and growth of beneficial
native bacteria in the gastrointestinal tract and eliminate the pathogenic
ones. Despite the potential benefits to health and growth performance as noted
in various terrestrial animals and fish, the use of prebiotics in crustacean
has been less investigated. The purpose of this review is to discuss the
effects of dietary prebiotics on growth performance, survival rate, digestive
enzyme activities and intestinal morphology in shrimp and crayfish cultivation.
The most commonly used prebiotics in such applications are
mannanoligosaccharides (MOS), fructooligosaccharides (FOS), GOS
(galactooligolosaccharide), isomaltooligosaccharides (IMO),
xylooligosaccharides (XOS) and inulin.
